mdm and nvidia libGL problem


I use webkit mode of mdm to login to Linux Mint. But I got a probability error:

[  104.541970] mdmwebkit[1812]: segfault at 8 ip b495c553 sp bf9ea850 error 4 in[b48da000+ad000]

It seems to happen in library. Since I cannot get the source code of nvidia LibGL, I have no idea what is happened.

Will somebody help me? Any suggestion will be appreciate.
